Example: Configuring PPPoE Encapsulation on an ATM-over-ADSL Interface

This example shows how to configure a physical interface for Ethernet over ATM encapsulation and create a logical interface for PPPoE over LLC encapsulation.

Requirements

Before you begin, configure network interfaces. See Example: Creating an Ethernet Interface.

Overview

In this example, you configure the physical interface at-2/0/0 for Ethernet over ATM encapsulation. As part of the configuration, you set the virtual path identifier (VPI) on an ATM-over-ADSL physical interface to 0, you set the ADSL operating mode to auto, and you set the encapsulation type to ATM-over-ADSL. Then you create a logical interface for PPPoE over LLC encapsulation.

Configuration

Step-by-Step Procedure

To configure PPPoE encapsulation on an ATM-over-ADSL interface:

Navigate to the physical interface
[edit]user@host# edit interfaces at-2/0/0
Set the VPI on the interface.
[edit interfaces at-2/0/0]user@host# set atm-options vpi 0
Configure the ADSL operating mode.
[edit interfaces at-2/0/0]user@host# set dsl-options operating-mode auto
Configure PPPoE encapsulation.
[edit interfaces at-2/0/0]user@host# set encapsulation ethernet-over-atm
Create a logical interface and configure LLC encapsulation.
[edit interfaces at-2/0/0]user@host# set unit 0 encapsulation ppp-over-ether-over-atm-llc vci 0.120

Verification

To confirm that the configuration is working properly, perform this task:

Verifying a PPPoE Configuration for an ATM-over-ADSL or ATM-over-SHDSL Interface

Verifying a PPPoE Configuration for an ATM-over-ADSL or ATM-over-SHDSL Interface

Purpose

Verify the PPPoE configuration for an ATM-over-ADSL or ATM-over-SHDSL interface.

Action

Enter the show interfaces command.

[edit]user@host#show interfacesat-6/0/0 {encapsulation ethernet-over-atm;atm-options {vpi 0;}dsl-options {operating-mode itu-dmt;}unit 0 {encapsulation ppp-over-ether-over-atm-llc;vci 35;}}pp0 {unit 0 {pppoe-options {underlying-interface at-6/0/0.0;idle-timeout 123;access-concentrator myac;service-name myserv;auto-reconnect 10;client;}family inet {address 11.1.1.1/32 {destination 11.1.1.2;}}family inet6 {address 2004::1/128 {destination 2004::2;}}family mpls;}}

Meaning

Verify that the output shows the intended configuration of PPPoE.
